close_storage_editor

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations supplied, the description carries the full behavioral burden and does disclose two useful traits: idempotency ('safe when already closed') and internal verification ('verify the window is gone'). It stops short of saying what happens if verification fails — whether it errors, retries, or returns a status — and a mutation with zero annotation coverage leaves that gap meaningful.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences, zero filler, with the action leading and the safety qualifier trailing. Every clause earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-parameter teardown action this is close to complete: it states the action, the idempotency guarantee, and that verification occurs. The only omission is failure/return semantics after verification, which matters slightly more here because no annotations or output schema exist to fill that in.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool takes no parameters, so the schema baseline is 4 and there is nothing further the description could add here. No parameter meaning is missing or contradicted.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb and resource ('Close the simulator's persistent-storage editor'), which is unambiguous and clearly distinct from any sibling such as stop_app or terminate_simulator. It stops short of explicitly naming what it is not, but no sibling overlaps this resource, so an agent can select it confidently.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

'Safe when already closed' cues the agent that calling it in an uncertain state is acceptable, which is genuine usage guidance. However, there is no explicit statement of when to reach for this versus other teardown tools (stop_app, terminate_simulator), so the usage context is implied rather than stated.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
